Fresh water is a limited resource, required by various sectors such as urban centres, industries, agriculture and so forth. With every passing day, the intensity of clashing demands for water are expanding and wastewater management seeming to be an only effective strategy to meet the ever-increasing demand for water. As per experts on the issues of wastewater irrigation, reuse of wastewater is a clear option for better management of our water resources, since the volume of wastewater is projected to increase significantly in future (Ambujam, et al., 1993). Therefore, this experiment work was carried out to examine the potency of using treated wastewater for the purpose of urban agriculture and its associated risks. To attain the objectives, a field survey was conducted in the month of January-2020; based on the collected data; multiple statistical techniques (Correlation, Regression and Time series analysis) have been applied, using SPSS. The outcomes of result indicate that treated wastewater could be a viable economic and ecological option if it is treated to the desired level. Keeping these things in view, author has enunciated this article as a case study in Delhi – a capital city of India.
